SAW-JOINTER.

SPECIFICATION forming part of Letters Patent N 0. 731,901, dated June23, 1903. Application filed March 30,1903. Serial Nb. 150.241. (Nomodol).1 all whom it may concern:

Be it known that I, EDGAR J. HICKS, a citizen of the United States,residing at Indianapolis, in the county of Marion and State ofIndiana,have invented certain new andusefulImprovements in Saw-Jointers,of which the following is a specification.

My said invention consists in various improvements in the details ofconstruction and arrangement of the parts of a combined saw jointer andgage of that general character shown in my former patent, No. 624,332,of

May 2, 189.9,all as will be hereinafter more fully described andclaimed. Referring to the accompanying drawings,

which are made a part hereof, and on which similar'reference charactersindicate similar parts, Figure 1 is a front elevation of a combinedsawjointer and gage embodying my said improvements; Fig. 2, a similar viewof thecentral portion thereof, showing the clamping-plate in the reverseposition; Fig. 3, aview similar to Fig. 2 with the clampingplate andoperating-cam removed; Fig. 4,

a central vertical section on the dotted line 4 4 in Fig. 2; Fig. 5, aperspective view of the clamping-plate, and Fig. 6 a similar view of thegage-plate.

In said drawings the portion marked A rep resents the base block orframe, B the gage plate, and O the clamping-plate.

The base block or frame A isof substantially the form shown insaid-former patent,

consisting of a suitable casting having ribs 1 and 2 and projectingpoints 3 on its front face, also vertical ribs 4, extending between iribs 1 and 2, in which are formed shoulders former patent.

tical way formed in the frame A and is adapti ed toslide verticallytherein. 50

It is retained in position by means of laterally-projecting wings c onits rear side and similar Wings 0' der which rests upon an operating-camO.

Said cam is mounted upon a cylindrical lug a, which projects from theface of the baseblock at a suitable point. The clampingplate C is put inplace by extending its upper end through the way in the base-block andturning it to position, bringing'the upper end thereof, with theprojecting wings a, through the widened upper portion of said way. Saidplate is then slid downwardly, with the wings c on the other side. Thescrew I), provided for securing gage-plate B in position, is thenscrewed downwardly until the gage-plate is firmly seated in position,when the point of said screw will be in position to prevent theclamping-plate C from being raised to a point where the wings 0 willclear the narrowed portions of the way in which said plate is mounted.Said plate is thus retained in position without the use of theretaining-screw used in the aforementioned Letters Patent, while it ispermitted a free vertical adjustment.

In operation, it being desired to use a file in horizontal position asfor jointing the points of the teeth, said file is placed fiat- Wisebetween the lugs 3 and the upper end of clamping-plate C, saidclamping-plate being in the position shown in Fig. 1. The cam. C is thenturned by means of its handle 0 until said file is firmly secured. Whenit is desired to use the file in a flat position, as when employed forjointing the sides of the teeth, it is placed with one edge restingagainst the shoulders 5 in the vertical ribs 4, and its other edge restsupon the lugo on the lower end of the clamping-plate C, the parts beingin the position shown in Fig. 1. The cam is then turned on its pivot tothe position shown in Fig. 2, when said file will be firmly clamped tothe base or frame and ready for use.

All reference to the top of the tool in the foregoing descriptionrelates to the drawing alone, as will be readily understood, the toolitself, strictly speaking, having no top.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a saw-jointer, the combination of the base block or frame providedwith a suitable way and aclamping-plate for the file, mounted in saidway and formed with wings on its opposite sides,which engage on oppositesides of said base block or frame, substantially as set forth.

2. In a saw-jointer, the combination of the base block or frame providedwith rests for the file in its different positions, and formed with acentral way for the clamping-plate, and said clamping-plate mounted toslide in said way, and formed with wings which project on each side ofsaid base block or frame, said clamping-plate being provided with restsor jaws for engaging one side of the file in its severalpositions,substantially as set forth.

3. In a saw-jointer, the combination of the base block or frame with avertical way for the clamping-plate, said way being widened at one end,the clamping-plate mounted in said way and formed withlaterally-projecting wings on its opposite sides, said wings on one sidebeing at one end and adapted to pass through said widened portion ofsaid way, a set-screw for limiting the motion of said clamping-plate,and a cam for operating it, substantially as set forth.

4. In a-saw-jointer, the combination of the base block or frame providedwith the rests for the file in its different positions, a gageplatesecured therein by a screw, the clamping-plate mounted in a centralvertical way formed in said base block or frame,said clamping-platebeing formed with laterally-projecting wings for engaging opposite sidesof said base block or frame, the wings upon one side being formed at itsend and adapted to pass through a widened portion of said way, saidscrew being of a length so that its end will come in position to limitthe movement of said clamping-plate after it is in operative position,and a cam for operating said clamping-plate, all substantially as setforth.

5. In a saw-jointer, the combination of the base block or frame providedwith rests for the file in its'diiferent positions and with a centralway, and a clamping-plate mounted to slide in said central way andformed with integral projections adapted to engage the sides of said wayand retain said clampingplate in place, substantially as set forth.

In Witness whereof I have hereunto set my hand and seal, atIndianapolis, Indiana, this 23d day of March, A. D. 1903.
